Project Background
Emphasis of Current Efforts Cost-Effective Use
of Prefabrication Techniques for Bridge
Components Advanced Materials Technologies, suc
h as Self Consolidated Concrete
Construction Methods, e.g. Stage Construction, U
se of SPMTs and Incremental Launching for Bridge
Superstructures

Project Background
What is Needed Fundamental Re-Thinking of the
Antiquated Processes that are still being used
to Deliver Bridge Projects

We are Nearing the End of an Era
Relied on Paper for Centuries, as a Primary Re
presentation for Engineering and Construction
Only Industry Producing 3D Products Using 2D Dra

Documented Reduced Costs, Faster Delivery and
Improved Quality Resulting from 3D Based
Integrated Design and Manufacturing Processes.

Project Background

• Piecemeal Progress in the Industry
• Parametric Design Tools and TransXML Omit
  Detailing for Fabrication and Construction
  
• 3D Pre-Cast Concrete Modeling Tools are not (yet)
  Bridge-Oriented
  
• Bridge Inspection or Design/Rating (e.g.) Apps
  each Require their own Data (Re)Entry
  
• 3D Geometry Created (e.g., Visualization,
  Structural Analysis) is not also Leveraged for
  Fabrication Construction, or Management
  Purposes
• Where Electronic Data Exchange is Pursued, only
  Pieces of the Overall Workflow are Involved

10
Project Background

• FHWA International Review Tour 1999
• - Prevalent CAD/CAM in Europe, Japan
• FHWA Workshop 2001 Computer Integrated Steel
  Bridge Design and Construction Expanding
  Automation
  
• Established a Roadmap for Integrating Steel
  Bridge Design-through-Construction Processes
  and for Advancing the State-of-the-Art Practice
  in Steel Bridge Manufacturing Automation and
  Productivity

11
Project Background

• Theme Areas Progress
• 3D Modeling Electronic Info. Transfer
• NCHRP 20-07 Task 149 Project (Completed Nov.
  2003)
  
• Standardized Specs and Approval Processes
  NSBA/AASHTO Collaboration
  
• Standardized Design Details
• NSBA/ AASHTO Collaboration
• Showcase of Benefits of Automation
• AASHTO Subcommittee on Bridges and
  Structures Resolution (2005)
  
• FHWA Project DTFH61-06-D-00037

What This Is About
14
Overview of Project Vision
Develop a Prototype Integrated System
Illustrating the Data Exchanges and Applications
Addresses entire Bridge Life Cycle Utilize 3-
D Bridge Information Modeling (BrIM) as a
Technology to Accelerate Bridge Project Delivery
and Enhance Life Cycle Management
Demonstrate the Viability, Efficiencies and Bene
fits of the Integrated Bridge Project Delivery
and Life Cycle Management Concept (POC)
15
Project Scope
A Large and Complex Project Relates Many Data Ex
changes and Stakeholders Involves Development o
f a Prototype - Not Production - Software Linking
Appropriate Existing Commercial Software that
Demonstrates a Viable Integrated System for
Bridge Project Delivery and Life Cycle Management
16
Project Objectives
Develop integration and linking software
Demonstrate utility of an integrated approach
Promote benefits and efficiencies of this approa
ch Develop and conduct one-half and two day wor
kshops Make presentations to illustrate use of
the system for concrete and steel bridges
17
Project Approach
Generate a 3D Architectural Blueprint for
Integrating Various Phases into the Automated
Processes Significantly Improved 2D Design Drawin
gs, as well as Construction Drawings, in
Conjunction with Life Cycle Management Through
Automation
